SULKY SPRING-TOOTH HARROW.

SPECIFICATION forming part of Letters Patent No. 779,378, dated January 3, 1905.

Application filed December 21, 1897.

To all whom, it nfl/ty concern,.-

Be it known that I, CHARLES S. SHARP, of Auburn, county of Cayuga, and State of New York, have invented an Improvement in Sulky Spring-Tooth Harrows, of which the following' d escription,in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object to improve the construction of sulky spring-tooth harrows; and it consists in providing a springtooth harrow of common form, composed,es sentially,of two harrow-sections loosely connected or hinged together, with a sulky attachment connected thereto by fieXible draft devices, whereby said snlky attachment. will be drawn by said harrow-sections and whereby said harrow-sections will be free to move independently of each other and of the sulky attachment, and, furthermore, whereby said sulky attachment may be held relatively to said harrow-sections with its wheels parallel to the line of draft and the rear portions of said harrow-sections held down in a yielding manner to assist the teeth in penetrating stubborn soil and whereby the rear portions ofsaidharrowsections may be held at dierent elevations relatively to the supporting-frame in order that the pitch of the teeth may be changed and whereby the operator is enabled to handle the harrow to the best advantage-z'. e. to operate the adjusting-levers,by means of which the harrow-teeth are raised and lowered and held in different elevations, and the harrowsections are carried at any desired height from the ground-and whereby the harrow may be at all times supported by shoes in front and wheels in the rear; yet means are provided for limiting the depth that the teeth shall penetrate the soil.

In carrying out this invention I may take an ordinary spring-tooth harrow comprising, essentially, two harrow sections which are loosely connected or hinged together, each section comprising, for instance, a frame and a set of harrow-teeth and means for raising and lowering said teeth and for holding them at di'erent elevations and aset of shoes or runners-as, for instance, a front shoe and a pair of rear shoes-and means to which the draft Serial No. 662,802.

devices will be connected, and I provide such a spring-tooth harrow with a sulky attachment which is confined within the boundaries of the harrow and which consists, essentially, of an arched seat-supporting frame disposed relatively to the harrow-sections, so as to cross the junction ofsaid harrow-sections, and bearing at its extremities a pair of wheels, and draftbars are provided for iiexibly connecting said arched seat-supporting frame with said harrow-sections. For simplicity of construction I may employ long slender draft-bars, the forward ends of which may and preferably will be pivotally connected to the forward ends of the harrow-frames and the rear ends ofwhich will be connected to said seatsupporting frame. Guideways are provided, which depend from said seat-supporting frame, which receive cooperative parts of the harrow-sections to thereby hold the said seat-supporting frame with its wheels in parallelism with the line of draft and to also permit said harrowsections to freely and independently rise and fall. Springs are interposed between the seatsupporting frame and the harrow-sections beneath it, which act to assist in holding down said harrow-sections.

Figure l shows in plan viewasulkyspringtooth harrow embodying this invention; Fig. 2, a side elevation of the same with the parts in the position they will occupy when the teeth are acting in the soil; Fig. 3, a vertical section of the same,'taken on the dotted line m Fig. l, the parts being in the position that they will occupy when the teeth are lifted and the harrow in condition for transportation; and Figs. 4, 5, and 6, details to be referred to.

In the particular form of harrow employed and to which my improvements are applied A A represent the main frames of the two harrow-sections, being shown as substantially U-shaped frames, and they are joined together by hinges a a. Each harrow-frame has a number of tooth-bearing cross-bars a2 mounted in depending brackets I), which are secured to the sides of said frame, and each cross-bar has a number of spring-teeth F, of any suitable kind, attached thereto in any suitable manner. Each harrow-section also has a set- IOO lever bar c connected to the cross-bars co2 by arms a3 and also a set-lever which is formed integral with or attached to one of said arms cf--as to the middle one, for instance-and the toothed quadrant c2, with which said setlever cooperates, is attached to said bar c.

Shoes D (see Figs. 2 and 5) are adjustably secured to the front end of each harrow-section-as, for instance, one such shoe may be applied to the draft-iron D2 on each section and with it secured to the front end of the frame-and additional shoes D' are attached to each side bar of each of said frames, they being herein shown as carried by brackets b2, which are attached to said frames and to the brackets b, and said brackets b2 are made adjustable, as shown in Fig. 2, wherein it will be seen that a slot is provided through which a bolt b3 passes, which connects said brackets L2 with said brackets b.

The sulky attachment consists, essentially, of an arched supporting-frame d, having stubaxles at the lower extremities of its wheelcarrying arms, and wheels B are mounted on said axles. The arched supporting-frame CZ is located above the two harrow sections above described and is set relative thereto so as to cross the junction of said sections, and said frame is made of such length as to terminate substantially midway the width of said sections, so that the wheels B will occupy positions within the frames, as shown in Fig. 1.

The supporting-frame d has depending from it at or near each end a pair of arms which are secured at their upper ends to said frame, and the arms of each pair are located near together to provide between them a vertical guideway. These vertical guideways are` so located as to receive in them the set-lever bars c of the harrow-sections and permit said bars to work longitudinally and vertically therein, and they also serve as a means of holding` the sulky attachment with its wheels in parallelism with the line-of draft and also permit the rear portions of said harrow-sections to freely and independently rise and fall. Springs E inclose said depending yarms c5, which bear upon said bars c and act to yieldingly hold down the harrow-sections. At the lower ends of the arms c5 several holes are formed, into any one of which a pin will be placed, upon which the bars c may rest, and as said pin is changed into one or another hole said bars, and consequently the rear portions of the harrow, will occupy different elevated positions, with the result of varying the pitch of the harrow-teeth.

Bars 02 are iixed at their rear ends to the supporting-frame (see Fig. 4) and at their front ends are loosely or pivotally attached to the front end of the harrow-frames#as, for instance, to the draft-irons, which are attached at such pointland additional bars 030 are attached to the bars 020 and to the supporting-frame to provide additional stiffness.

The bars 020, by which the supporting-frame is attached to the harrow-sections, are long and slender and capable of being easily bent or twisted, thereby permitting the harrowsections to move independently of each other and of the supporting-frame. By pivotally connecting the front ends of the bars 02 to the harrow-frames it will be seen that the rear portions of the harrow-sections are free to rise and fall independently of said frame. A seat -is mounted upon a spring-support which is secured to said supporting-frame, and said seat-support is strengthened by bars 5 and 6, to the front ends of which is attached the foot-rest 7.

The rear shoes D and the sulky-wheels B are so set relatively to each other that the tread portions of said wheels always occupy a position below the tread-surfaces of said shoes, so that the harrow will be supported upon or by the front shoes D and sulky-wheels at all times; yet the rear shoes D are provided to limit the depth that the harrow-teeth will enter the soil if the wheels should enter a rut or other depression.

The harrow herein shown may be set with its teeth in position to penetrate the soil, as shown in Fig. 2, or said teeth may be thrown into the position shown in Fig. 3 for the purposes of transportation.
